方法详细资料

setRepositorySelector

public static void setRepositorySelector(RepositorySelector selector,
                         java.lang.Object guard)
                                  throws java.lang.IllegalArgumentException

Sets LoggerFactory but only if the correct guard is passed as parameter.

Initally the guard is null. If the guard is null, then invoking this method sets the logger factory and the guard. Following invocations will throw a IllegalArgumentException, unless the previously set guard is passed as the second parameter.

This allows a high-level component to set the RepositorySelector used by the LogManager.

For example, when tomcat starts it will be able to install its own repository selector. However, if and when Tomcat is embedded within JBoss, then JBoss will install its own repository selector and Tomcat will use the repository selector set by its container, JBoss.

抛出:

java.lang.IllegalArgumentException

getLoggerRepository

public static LoggerRepository getLoggerRepository()

getRootLogger

public static Logger getRootLogger()

Retrieve the appropriate root logger.

getLogger

public static Logger getLogger(java.lang.String name)

Retrieve the appropriate Logger instance.

getLogger

public static Logger getLogger(java.lang.Class clazz)

Retrieve the appropriate Logger instance.

getLogger

public static Logger getLogger(java.lang.String name,
               LoggerFactory factory)

Retrieve the appropriate Logger instance.

exists

public static Logger exists(java.lang.String name)

getCurrentLoggers

public static java.util.Enumeration getCurrentLoggers()

shutdown

public static void shutdown()

resetConfiguration

public static void resetConfiguration()
